To all whom t may concern u Be it known thatI, ELMER E. I-IAUER, a citizen of the United States, residing `at Springeld, in the county of Clark and State of Ohio, have invented certain new and useful Improvementsin Rotary Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to Vrotary motors and more articularly to a motor .for driving tube cleaners that is adapted to travel through a tube with the cleaner, although it may beused for other purposes. A motor for the purpose named must run at a high speed and be limited in its dimensions by the size of the tube in which it is kto operate. Furthermore the conditions of service vary according to the thicknes and hardness of the scale to be removed. My present-J motor is designed to meet conditions where the service is severe and the dimensions are necessarily limited; and to that end a bearing is provided in which one parthas a sliding contact in its rotation about a stationary part, the contacting surfaces being inclined to the axis of the motor `to both carry and take the end thrust of the rotary motor member.; and further means are provided to take up the wear of the bea-ring. This bearing is preferably employed in combination with another bearing as will hereinafter more fully appear.

`With these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth inthe claims. l

In the accompanying drawings which form a part of this specification Figure lis a longitudinal section on the line 1-1 of Fig. 2 and Figs. 2, 3 and 4 are cross-sections on the lines 2 2, 3-3 and 1 -4 respectively of Fig. 1.

in the several views V.

In the drawings 1 represents a supply head having a chamber 2 and a wall 3 in Like numerals represent the same"` parts',

front of said chamber. Said wall has a forwardly projecting cylinder l and a forwardly projecting shaft 5 and said wall, cylinder and shaft are preferably formed integral with said head.

A rotary motor member 6 has a forwardly and rearwardly extending cylinder 7 and the forwardly extending portion is pro- `Specieation*of Letters Patent.

` vided with screw-threaded end 8 to attach the tool to be driven. i

VThe bearings are mounted upon the'stationary shaft 'and disposed upon opposite lsides of the rotary motor'member within the respective ends of the cylinder of said PatentedJuly 7, 1914. ,i Application led January 218, 1914.,v SerialNO. 815,069.

member and I preferably employ bearings Y Qarranged to both carry and take the end .thrust of the rotary motor member. One of n. these `bearings whichwill be called a bush orcone bearing is shown as having ia lsleeve 9, the exterior of which has an in- )clined or cone-shaped surface 10 and is screw-threaded on the shaft'; and a sleeve or bushing 11 is seated within the forward end of the cylinder 7 against a shoulder 1,2. Said sleeve or bushing 11 has an inclined or cone-shaped bore vof thesame inclination to the axis of the motor vas the surface 10 of .the sleeve9 upon which, in its rotation,` it has a sliding contact that both carries and .takes the end thrust of the rotary motor member. The sleeve 9 can be adjusted `on the shaft 5 to .take up the wear of the bearing and a loclr-nutl is provided to hold it in adjusted position. The other bearing which will' be called a roller bearing is 'shown as having a sleeve or cone 14 on the shaft 5 seated against a shoulder 15 of the` `shaft and vheld in place' by a lock-nut 16; and a sleeve or bushing 17 with screwthreads 18 to which the rear end of the l upon the inner inclined surface of the sleeve i bushing 17; and said rings are held in place 4by* pins 23 tightened in openings in the respective rings so that when therollers are in place they will be held in assembledposition by said rings when the sleeves 14 and 17 are removed. It will be seen that this bearing also both carries and takes the end thrust ofthe rotary motor member; and the nut'16 holds the rotary motor member and l i both bearings in operative position.

The rotary motor member 6 is shown in the form of a turbine screw-threaded to the havingia shroud 25. yThe supply head has wall 3 and cylinder 4 and discharge l.intoY the buckets 24 of the rotary motor member;

"A shell 29 screw-threadedV at its rear end against a shoulder 30 of the head forms a casing that projects beyond the rotary motor member as shown. f

The motor is assembled by firstv placing therear bearing and securing itin position by the nut 16, the shroud 28 already being in place; then screw the sleeve 9 and adjust nut llof the .front bearing on the shaft; thenzthe shrouded rotary motor member is secured in place von its cylinder with thel sleeve bushing l1 in position within the cylinder; then screw the rearfendA of thecylinder to the sleeve 17 ofthe rear bearing; inserting a bar in the'opening 3l to keep the sleeve from turning and secure the casf ing to the supply head. Lubricant is sup-y plied Vto the bearings. throughan opening 32 having a screw-plug 33 to close the same'. The yconstructions shown'but not claimed herein are' claimed in my application Serial i Number 782,439,1filedfAug. lst, `1913;

Having thus described my invention claim 1. In a rotary motor, asupply head having a chamber with a wall vin frontof said chamber having ports therethrough and a central forwardlyl projecting shaft, said wall and shaft being formed integral with said head and 'a rotary motor member having a'bearing on said shaft, said bearing comprising a cone secured to said shaft-anda sleeve orbushing bored to fit and'have a sliding contact with Lthe surface vof said' cone, substantially as described.v

` 2. In a rotary motor, a supply head hav-l ing a chamber ywith, a wall in front of said chamberfhaving ports therethrough and a central 'forwardly projecting shaft, said wall andfsha'ft being formed integrally with saidhead and a rotary motor memberhavcylinder with removable, bearings for the respective ends thereof mounted onsaid shaft and means to maintainthe same thereon, one
